Abstract

A process of removing methanol from a mixed stream comprising methanol and at least one hydrocarbon and uti­ lizing the hydrocarbon as feed for an acid catalyzed alkyla­ tion unit which produces a spent acid stream is provided. The process is comprised of the steps of contacting the mixed stream with at least a portion of the alkylation unit spent acid stream whereby the methanol is reacted therewith and an aqueous reaction mixture is formed, separating the aqueous reaction mixture from the hydrocarbon and conducting the hydrocarbon to the alkylation unit.
